Secured in-anyfsuitable manner to the up 110 per side rails 11 of themotor car frame and adjacent to the upper ends of uprights 13 arehorizontally disposed pairs of rails 30 latter when tightened, will locksaid nut or collar in its adjusted position upon the threaded shaft.

While not in use, the improved motor car lifting mechanism 00 cupy thepositions illustrated in Figs. 1 and 2. The vertically sliding framecomprising the parts 16, 17 and 18 is held in its elevated position byengagement of locking bolt 29 1 in the lower one ofthe apertures 27 inthe liftingbar 25 and bar 31 is moved into a position to one side of thevertical plane occupied by the sliding frame and threaded rod 32 isscrewed, downward in said bar and being held in such position bytightening set screw 36 in nut or collar 35.

To reverse the position of the motor car upon the track rails or toshift its position 7 so that it can be placed on the rails of a crossingtrack, locking pin 29 is Withdrawn from the aperture in which it ispositioned and the sliding frame is permitted to move downward until thefoot plate 23 rests upon the road bed. Threaded rod 32 is nowmanipulated so. that it is moved upwardly through bar 31 until its lowerend occupies a horizontal plane that is occupied by the bearing block 19after which rod 32 is moved forwardly or toward the sliding frame sothat the lower end of the threaded rod can be positioned directly on topof said bearing block 19.

By means of hand wheel 34, the threaded rod is now manipulated so thatit will move downwardly through rail 31 and as this operation iscontinued, the lower end of the threaded rod'will bear on bearing block19 that is positioned on the upper end of the sliding frame, andconsequently the latter becomes a supporting member for the motor truckand which latter is lifted until its wheels clear the tops ofthe trackrails. The entire motor car and parts carried thereby is thus supportedon a single hearing, namely, the foot plate 23, and while thus elevated,the motor car must necessarily be held in a steady position by theoperator to prevent its tilting in one direction or another. While thuselevated and with the wheels above the track rails, the

various parts of my 7 motor car can be turned end for endso as toreverse its position upon the track or it may be turned part way aroundso as to position its wheels upon the rails of a crossing track and whenbrought to proper position the operator manipulates the screw rod so asto ,move the same upwardly through 7 rail 31, thus permitting the motorcar to gradually descend upon; the sliding frame which constitutes thesupport until the wheels of the truck are positioned upon thetrack:rails. a

In the event that it is desired to lock the lifting mechanism while thetruck is in ele-' vated position, this can be accomplishedby positioningthe end of locln'ng bolt 29 in the lower one of the apertures 27 inlifting rod 25. 7

Under normal conditionsor while not in service, the sliding frame iscarried so that the foot plate 23 occupies a plane approxin mately eightinches above the surface of the w road bed.

A lifting and swinging support for motor.

cars of my improved construction is comparatively simple, occupiescomparatively. little space upon the motor car, and provides simpleandefficient means whereby the operator of the car can readily reversethe.-

position of the car upon the track or shift the position of said car sothat it may be placed upon the rails of a crossing track.

It will be readily understood that minor, changes in the size, form andconstruction I of the various parts of my improved device may be madeand substituted for those herein shown and described, without departing.7

from the spiritof my invention, the scope of which is set forth in theappended claims.

I claim: 7 v r i 1. The combination of a car, a member arranged to slidevertically thereon,:fixed guideways on the car fOIfSitld member, a

lifting membermovably mounted on said 1 car and normally out ofoperative relation to said vertically sliding member,and means foroperating said lifting member when: in A engagement with said slidingmember to raise said car. l

2. The combination of a motor car, a mnipulative' member arranged toslide vertically thereon, fixed guideways on the car for said member,arotatable bearing on the lower end of said sliding member, and amanipulative threaded member normally out of engagement with saidvertically sliding member and movably mounted on said motor car andarranged to be placed in operative engagement with said sliding memberto lift the car on said rotatable bearing.

3. The combination of a motor car, a manipulative frame member arrangedto slide vertically thereon, a rotatable bearing on the lower end ofsaid sliding frame'mem her, a manipulative j ack-screw normally out ofengagement with and carried by said motor car and arranged to be placedin operative engagement with said sliding frame member to lift the caron said rotatable bearing, and a collar on said jack-screw foradjustably limiting the lifting movement of said threaded member;

4. The combination of a car, vertical channel bars mounted thereon amanually operable member arranged tor vertical movement in said channelbars, flanged members connected to said channel bars, a transverselydisposed horizontal sliding bar mounted between said-flanged members, a

cally sliding member, and a rotatable bearing mounted on the lower endof said vertically sliding member, said bearing being below theapproximate center of gravity of the entire car. r

In testimony whereof I hereunto afi'ix my signature this 27th 'day ofOctober, 1919.
